“How do you prove if someone is gay or straight?” he said. “One of the most disturbing things about the league’s position in this case is that there’s only one way of being gay, or one view of being gay. The definition did not include bisexual, or transgendered. Our clients break the stereotypes of what gay is supposed to be.”

Since the lawsuit was filed, the North American Gay Amateur Athletic Alliance has changed its definition of gay to include bisexual and transgender people. It also clarified that it would determine sexual orientation by self-declaration.

The implications of the lawsuit stretch beyond the clarification, said Helen Carroll, the sports project director at the National Center for Lesbian Rights. She said she hoped it would spotlight the often-overlooked issues that face bisexual athletes and highlight the movement in gay sports leagues away from such limits.
